Simon Cowell has finally shown us all his magical singing voice - and what better way to debut it than by singing Go Go Power Rangers?

But the father-to-be didn't let a silly thing like pride stop him when he heard it was for charity - well done Simon, we are proud.

He was at the Friends of Israel Defence Forces charity fundraiser in Beverley Hills on Tuesday when billionaire Power Rangers creator Haim Saban offered to donate $1million if he sang the show's theme song.

And much to our delight he obliged in front of the startled crowd.

The 54-year-old star jokingly asked half way through if he could stop, and offered £100,000 of his own money for the privilege.

Saban told him he would allow it for £250,000 and Simon, breathing a sigh of relief, agreed.

And it's the second of the star's big surprises this year, after his girlfriend Lauren Silverman announced she was pregnant with his baby.

Maybe he can use his oh-so-tuneful voice to help his baby get to sleep? We don't think so somehow.
